STRESET – Reset Your Stress and Strengthen Your Well-being Streset is a smart stress management and well-being app designed to help you restore balance between body and mind. The app combines physiological measurements, self-assessment tests, and personalized exercises – all based on evidence and practice. Understand Your Stress Better Streset tracks your body’s functions – such as heart rate variability, heart rate, and blood pressure – and helps you observe how stress and recovery appear in your body. Through guided tests, you can identify the state of your nervous system and gain a clearer understanding of how your body responds to everyday demands. The app includes a variety of tests and questionnaires that help you monitor your well-being and recovery: Stress Response Test shows whether your body is in fight, flight, freeze, or recovery mode. Autonomic Load Test indicates how strained your autonomic nervous system is. BODY Movement Analysis helps you notice tension, pain points, and imbalances in your body. Additional Questionnaires (MAIA, BPQ, ERQ, SLEEP) provide deeper insight into body awareness, emotional regulation, and recovery. Based on your results, Streset offers personalized recommendations and exercises that support recovery, relaxation, and mental clarity. Exercises for Body and Mind Streset provides a wide range of guided audio and video practices grounded in movement, mindfulness, and breathwork. Movement exercises help you recognize and release tension, improve mobility and flexibility, and support physical recovery. Awareness practices strengthen your ability to pause and return attention to the present moment. Breathing practices help calm the nervous system and restore inner balance. These practices enhance the connection between body and mind, reduce stress, and support overall well-being in daily life. Track Your Progress In the results section, you can see the state of your nervous system and how it changes through regular practice. Visual charts display trends in HRV, heart rate, and blood pressure, helping you understand how stress and recovery are reflected in your body and mind. Evidence-Based and Practical Streset is built on years of experience in body–mind work, combining psychiatric nursing, somatic therapies, mindfulness, breathing guidance, movement practices, and fascia methods.
